Help with autometer wiring?

OK, so I got all my autometer gauges wired. Replacing the stock panel in my 72 Demon. I installed a voltmeter, removed the alternator amp gauge. I just soldered the two amp gauge wires together and taped them really well. (black and red). Now, I understand that the blue with white tracer is the power on feed which passes through the ignition in the key on position to power up all my instrument cluster gauges? So, I took off from the blue with white tracer and jumped from instrument to instrument to feed every gauge. I then ran a separate wire the same way to all the grounds, which will get grounded in two places under the dash frame. Then I color coded the remaining wires to feed the actual signals. My question is, am I correct in the blue with white tracer feeding the gauges thru the ignition switch? I also ran a separate wire from the lights on switch to all the gauge lights and just jumped from one to the other and then a separate ground jumping them from one to the other and that will be grounded to the dash frame. I was going to go out and buy my battery now and set up alligator probes to test out each circuit while this is on the bench. Does this sound like a good plan. I also fixed the ebrake indicator light (the black wire) by powering up a feed thru the ignition switch again and the black goes to the separate ground which activates that little red light when the ebrake is pulled up and grounds the circuit with the plunger type switch.
